Celebrity Trainer: Ashley Borden

After having a baby, most women’s biggest concern is strengthening the pelvic floor again. The best way to do that, says Borden, is the plank—done properly.

“A plank is your BFF,” she says. “And when you’re strict about your form, your body will change so much faster than if you do a bunch of fancy moves incorrectly.” Keep your focus on proper form as well as the length of time you can hold the position—and keep track of it. “A month from now, you’ll see how far you’ve progressed, which is really motivating,” Borden says.
